Stefani Joanne Angelina Germanotta (/ˈstɛfəniː dʒʌrməˈnɑːtə/ STE-fə-nee jurr-mə-NAH-tə; born March 28, 1986), known by her stage name Lady Gaga, is an American singer and songwriter. Born and raised in New York City, she primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She began performing in the rock music scene of Manhattan's Lower East Side, and was signed with Streamline Records by the end of 2007. During her employment as a songwriter for the record company, her vocal abilities captured the attention of recording artist Akon, who signed her to his label Kon Live Distribution.

Lady Gaga came to prominence as a recording artist following the release of her debut album The Fame (2008), which was a critical and commercial success that topped charts around the world and included the international number-one singles "Just Dance" and "Poker Face". After embarking on the The Fame Ball Tour, she followed the album with The Fame Monster (2009), which spawned the worldwide hit singles "Bad Romance", "Telephone" and "Alejandro". The album's success allowed her to embark on the eighteen-month long Monster Ball Tour, which later became one of the highest-grossing concert tours of all time. Her most recent album Born This Way (2011) topped the charts of most major markets and generated more international chart-topping singles, including "Born This Way", "Judas" and "The Edge of Glory". Besides her musical career, she involves herself with humanitarian causes and LGBT activism.

John Gilbert "Jack" Layton, PC (July 18, 1950 – August 22, 2011) was a Canadian social democratic politician and Leader of the Official Opposition. He was leader of the New Democratic Party from 2003 to 2011, and previously sat on Toronto City Council, occasionally holding the title of "Acting Mayor" or "Deputy Mayor" of Toronto during his tenure as city councillor. He was the Member of Parliament for Toronto—Danforth from 2004 until his death.

Son of a Progressive Conservative cabinet minister, Layton was raised in Hudson, Quebec. He rose to prominence in Toronto municipal politics where he was one of the most prominent left-wing voices on city and Metropolitan Toronto councils, championing many progressive causes. In 1991, he ran for mayor, losing to June Rowlands. Returning to council he rose to become head of the Federation of Canadian Municipalities. In 2003, he was elected leader of the federal NDP on the first ballot of the convention.

Under his leadership, support for the NDP increased in each election. The party's popular vote almost doubled in the 2004 election, which gave the NDP the balance of power in Paul Martin's minority government. In May 2005 the NDP supported the Liberal budget in exchange for major amendments, in what was promoted as Canada's "First NDP budget". In November of that year, Layton voted with other opposition parties to defeat the Liberal government over the findings of the Gomery Commission. The NDP saw further gains in the 2006 and 2008 elections, in which the party elected 29 and 37 MPs, respectively.
